Microsoft has announced its plans to release three free software updates to fix security holes in its products, including two vulnerabilities in Windows and another in its Exchange Server corporate e-mail product.
At least one, possibly both, of the Windows patches will carry a 'critical' rating -- Redmond's most severe. Microsoft considers a flaw "critical" if the vulnerability could be used by attackers, viruses or worms to seize control over a targeted computer without any action on the part of the victim. The Exchange patch also will come with a ‘critical’ label.
Security Fix will have more details about them as soon as they're released.
